i Application filed .iirne 19. 1911. Serial mesaaev.

To all W s/10m it may concern i lie it known that I, FREDERICK I'l .Ioux, a citizen of the-United States, residing at liliddleport, in 'the county of Schuylkill and State of Pennsylvania, have invented a new and useful Spring-heel, of: which the following is a specification.

It is the object of the presentinvention to provide a wheel, the spokes of which are resilient, and olnovel form, whereby the pneumatic tires commonly used, may be dis- -pensed with.

A further object of thinvention is to provide novel means for assembling the spokes with the hub of the wheel, and to provide novel means for adjusting the rim of the wheel, to' engage with, and to hold the tire.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details or" construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, Figure 1. is a fragmental side elevation. of .a wheel constructed in accordance with my invention; Fig. 2 tion; Fig. 3 is a side elevation of the spokeplate from which the spokes extend; and Fig. l is a detail perspective of the meeting ends of the rim.

In carrying out the invention there is provided as a primary and fundamental element, a spoke plate'denoted generally bythe numeral 1. From the spoke plate 1 extends a plurality of spokes, denoted generally by the numeral. 2. The spokes 2 are formed integrally withthe plate 1, and the inner ends 3 of the spokes 2 are. disposed in a common plane with the plate 1. Beyond the portions 3, the spokes 2 are twisted. as shown at 1, so that their body portions 5 lie in a curved surface, at right angles to the plane of the body 1. The portions 5 of.

the spokes are curved in a common direction,

the extremities (3 of the spokes lying in ais a fragniental transverse sec-' without, the use of pneumatic tires.

at. one-end, may be enlarged slightly, as

shown at 10, to receive the other end ll of the rim. The rim, adjacent its meeting ends. provided with lugs 12. A screwllis right and left hand threaded into the lugs 12, and it will be seen that, after the tire 9 is loosely engaged about the rim 7, the screw 11 may be rotated, to causethe end 11 of the rim to slide in the end 10, thereby expanding the rim, and holding the tire 9 tightly in place upon the rim. it will be seen that the manner of mounting the tire 9 in place, and of removing the same, may be carried on in a simple manner, and without ditiiculty, by the owner of the vehicle.

In the central portion of the plate 1 there is an opening 15, through which extends a bushing 16. mounted upon the ends of the bushing 16, the hub members 17 having upstanding From the roregoing Spaced .hub members 17 are flanges 18, between which the plate 1. is inv closed. Bolts 19 or other connecting elements adapted to a like end, may be extended through the flanges 18 of the hub mem bers 17, and through the spokeplate 1, to hold the parts assembled, as seen most clearly in Fig. 2.

It is of course understood that the portions 5 of the spokes are resilient. and thus, the tire and the rim will be yieldingly supported, the desiredre'siliency being obtained The wheel is so constructed that it will be suiticiently resilient. without being unstable. Owing to the fact that the spokes 2 are formed integrally with the spoke plate 1, and owing to the fact that the spoke plate is bound firmly between the hub membe s 17 the wheel, in its hub portion. is male of unusual strength. In wheels which are provided with resilient spokes,'a great strain is imposed upon the hub, and the hub, in the wheel of the present invention, is so designed that it will adequately bear the strain above referred to.

Having thus described what is claimed is 1.-In a device of the class described. a

In testimony thatI claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
